TTL to Open Collector Converter PCK3

Suitable for optical incremental encoders with single ended TTL output A, B, Z (Index)

The application of the PCK3 is the conversion of output signals A, B, Z (index) from an optical incremental rotary encoder, from TTL level to open collector circuit outputs. The open collector circuit allows a level conversion and a maximum pull-up voltage up to 35 V. Thus, signal cable lengths between rotary encoder and evaluation unit until 150m can be realized. On demand external pull-up resistors can be connected between the signal outputs of the PCK3 and VSUP to adapt the PCK3 to the evaluation unit optimally. Thanks to the variable supply voltage range, the PCK3 can be used flexible and supplies the connected encoder with a stabilized supply voltage of 5 V/DC.
